VEHICLE STEER'NG MECHANISM.

Application tiled August 30,1920. Serial No. 406,931.

a steeringy wheel lock in which the key to the bolt actuating` lock may be withdrawn after the lockingbolt has been moved thereby to either oiE its normal limits. Another object ot my invention is to provide a simple, cheap and effective locking device whereby the steering gear of a motor vehicle may be rendered inoperative to unauthorized persons. Av third object of my invention is to provide improved anti-friction bearing means between the steering; wheel and steeringr post. Other objects oit' my invention are mentioned and described herein.

The preferred embodiment of my invention is illustrated in the accompanying drawing' in which Figure 1 is a sectional side elevation of a steering wheel in fragment. steering post, and other members, to which my invention is applied, in which iiojure the locking' bolt is retracted and the steering' wheel is independently rotatable on the steering' post; Fig. 2 is a view showing the tumbler lock, pinion and other members for actuating the locking'bolt.; Figt is a section taken on the line eti-Fig. 2; Fifi. el is a side elevation view ot the driver huh or collar; Fig. 5 is a view showing the ball bearing sleeve in side elevation and in section; Fig. 6 is a plan view of the shaft for carrying` the rboltactuationpinion; and Figi'. 7 is a iront elevation ot' the same member.

Similar like members throughout on the drawing.

Referring' to the details ot the drawing, the numeral 1 indicates the usual hollow cylindrical steeringr column within which the usualy cylindrical. or any type of, steering post 2 is arranged. the latter being' adapted for connection with the steering rfear-not shown-ot the vehicle. as is well known in the particular art.r Numeral indicates a hollow cylindrical driver hub rigidlymountnumerals ot' reference indicate the several viewsr ed upon the top end of the'post 2 to which it may be keyed-by a key 4L to prevent rotative movement thereof on said post. A nut 5 may be screw threaded upon the post 2 above the driver hub 3 to confine the latter against longitudinal movement on or` displacement :trom the post. The hub member 3 may have the radially formed bolt socket 6 intermediate the two circumferential grooves 7 and 8, said grooves' being adapted to serve as ball races or containers, as hereinafter described. f TheA numeral 9 indicates a hollow cylindricall ball bearing' sleeve member encom-` passing;` the hub 3, the bore of said sleeve being slightly larger than the exterior diameter of said hub, said sleeve bore having the two annular endless grooves 10 and 11 formed therein which are. adapted to cooperate with the hub grooves 7 and 8, respectively, to carry the anti-friction balls 12, a plurality of which are mounted in each of said groove units. The sleeve 9 is pro-vided alsowith the bolt aperturel 13 which is adapted to be placed in registration with the bolt socket 6 `formed in the hub 3. Numerals 14 and 15 indicate upright slots formed. respectively, in the hub 3 and sleeve 9 and communicating respec.

tively., with the grooves 7 and 10 to enable the introduction ot a suitable number of the balls 1.2 into said cooperating' grooves. The

numerals

16 and 17 indicate upright slots formed respectively. in the exterior of the huh 3 and the bore of the sleevey v9 and comn'iunicating respectively, with the grooves Sand 11 to enable the introduction ot :i suitable number of the balls 12 into said (grooves, the slot 17 having its upper end in communication with the orifice 13 through which said balls maybe passed when said slots are brought into registration. y

rlhe numeral 18 indicates a steering wheell hub which may be provided with the usual. spider arms 19` 19, said wheel hub being bored to detachablv encompass the sleeve member 9, the upper end of said hub bore beine provided with the annular shoulder portion 20 which lengages the upper end of said sleeve and bv which said wheel may be wholly carried. The numeral 21-indicates a casing proj ecting laterally `from the wheel hub 18 and provided with a radially arranged bolt chamber 22 which is disposed axially ot the sleeve orifice 1.3, the kinner end nov certain', tumbler's-n'ot of said bolt chamber being` in communica-v tion with said sleeve orifice and the outer end thereof being closed bv a plug' 23: locking bolt 24 is slidablv arrangedwvithin the chamber 22 and adapted to' be' alter-y nately moved into and out of engagement with'the hub socket 6 through th'esleeve oriiice 13 to effect a locked or unlocked relation between the whe'el hub 18 and the driver hub ,3. y Normally, when the bolt 24 is retracted trom thehub socket 6, its inner end is'l disposed rwithin lthe sleeve oriiice 13, as indicatedfin Fig. l, whereby the wheel and sleevep)V are lfree to rotate together on the balls 12l around the collar 3 and whereby displacement. Of the wheel hub 18 romfthe sleeve 9 is prevented. Ubviously, the sleeve Q Ijsheld against axial movement relative toA the post v2 by the balls 12 operating` in" theirI respective races, as described.

VDisposed in the casing' 21 and transversely oi the bolt chamber'22` isa tumbler lock 25 f s v-JV. Suitable type, said lock having,` a

`revoliible key barrel 26, as is well known,

which barrel is held against rotation by shown-when the lock keyfnot shownis withdrawn therefrom, as is well Iknown in the art. A pinion shaftv27 be rigidly mounted upon the linner end and axiallyof thekey barrel`26,

being .suitablyy flanged at 28 forV that purpose. A tooth pinion or gear 29 Vis revolubly mounted upon the shaft 27 and convxtined thereon by a nut 80. A lost motion device between't-he shaft 27 and the pinion 29 is effected by anlug' 31, carried on the end ottheypinion 29, and :a lug 32 projecting' from the shaft flange 28, the,` pinion lug4 libeing' arranged in the path of movement ,ofthe 1,119,232 when the .key barrel 26 is rotated by the key controlled and actuated bythe operator.

rA tooth rack 33 may be iformedon the bolt 24: with which rack the pinion 29 is incon'staiit mesh. A spring' 84 may be provided within the chamber'22 to bear against the bolt 21]; toy aid in the ,forward movement thereof. The bolt 2li may be cut away at 35 for a portion oit its length and a hook membere may bev rigidly secured to the bolt within such Acutaway portion.A A stop member may be screw threaded into the casing; 21 transversely ot' the bolt chamber',

, the inner ,end of said stop member projectbol-,t out away portion 35. annularcircumferential groove 37 may be formed in the stop member '36, said -@groovel beine; 'adapted to`be engaged by the point ,of the lio'o/k'BS, whichis rigidly secured to the bolt 24, such engagement being effected when the bolt is, retracted from the socket 6,

whereby removallof saidl stop. member is'I Pfieetfl- In the practical application of inventon ."th'hub 3, the 'sleeve `9 and the bearing balls 12 are assembled, as described, as a unit, the hub 3' of said unit being thereafter keyed to the steering post. rl`hereafter, the wheel hub 18 may readily be mounted 1n ven'compassment el" the sleeve 9 `by removing the stop member and retractinsthe bolt 2e ywholly within the bolt ychamber 22, and thereafter projecting the bolt 24 into the hub socket 6 and vreplacingthe stop member 36. Then a removal oi' the steering wheel is desired, the bolt 24; is first projected into the socket 6 of the hub 8, therealjiter, the stop screw 36 is removed which f enables the ready retraction et the bolt 241; out of both socket 6 and sleeve oriiice 13. In Fig'. 3* of the drawing` the relation oi the lost motion lugs 31 and 82 is illustrated when the bolt 24 is retracted with its point arranged within the sleeve orifice 13, in which position the tumblers or the lock 25 act to restrain the bolt against the action of the spring,- 84C.' y i Also, the position oi' the members as shown in Fie". 3 of the dr'awiirq` enables the re moval of the key :trom the barrel 26 of the may be made in the form, construction and arrangement ofthe parts without departing from the -spirit and scope of the invention o1 sacrificing' any ot its materialadvantages.
